New study suggests culling animals who ‘don’t belong’ can be a flawed nature conservation practice
2024-02-01
New research published today in the journal Science has concluded that eradicating animals on the basis that they are not native in order to protect plant species, can be a flawed practice costing millions of dollars, and resulting in the slaughter of millions of healthy wild animals.
Introduced large herbivores, or megafauna, are claimed to have distinct and harmful ecological impacts, including damaging sensitive plants and habitats, reducing native plant diversity, and facilitating introduced plants. However, up to now these impacts have been studied without comparison to a proper ...

Small RNAs take on the big task of helping skin wounds heal better and faster with minimal scarring
2024-02-01
Philadelphia, February 1, 2024 – New findings in The American Journal of Pathology, published by Elsevier, report that a class of small RNAs (microRNAs), microRNA-29, can restore normal skin structure rather than producing a wound closure by a connective tissue (scar). Any improvement of normal skin repair would benefit many patients affected by large-area or deep wounds prone to dysfunctional scarring.
Because the burden of non-healing wounds is so significant, it is sometimes called a “silent pandemic.” Worldwide, costs associated with wound care are expected to ...
Rural placements for medical students feed ‘pipeline’ for new family docs
2024-02-01
EDMONTON — New research shows an innovative education program is helping to address Alberta’s rural doctor shortage by making it more likely medical students will set up a rural family practice after graduation.
The University of Alberta was one of the first medical schools in Canada to set up its Rural Integrated Community Clerkship program back in 2007. It sends up to 25 third-year students for 10-month intensive work experiences with a single or small number of teaching physicians.
Instead of rotating to a new specialty placement every four to six weeks as in an urban ...
Zebrafish navigate to find their comfortable temperature
2024-02-01
All animals need to regulate their body temperature and cannot survive for long if it gets too high or too low. Warm-blooded organisms like humans have various ways to do this. They release heat by sweating or expanding the blood vessels in their skin, while shivering or burning fat in their brown adipose tissue has the opposite effect.
Cold-blooded animals such as the zebrafish, by contrast, cannot do any of these, so they have a different strategy. They look for places nearby that are at their “comfortable temperature,” just like how we might go out into the sun when we feel chilly or seek out some shade once it gets too ...
Buck scientists discover a potential way to repair synapses damaged in Alzheimer’s disease
2024-02-01
While newly approved drugs for Alzheimer’s show some promise for slowing the memory-robbing disease, the current treatments fall far short of being effective at regaining memory. What is needed are more treatment options targeted to restore memory, said Buck Assistant Professor Tara Tracy, PhD, the senior author of a study that proposes an alternate strategy for reversing the memory problems that accompany Alzheimer’s disease and related dementias.
Since most current research on potential treatments for Alzheimer’s focuses on reducing the toxic proteins, such as tau and amyloid beta, that accumulate in ...
Researchers identify critical pathway responsible for melanoma drug resistance
2024-02-01
(Boston)—One of the major challenges in cancer research and clinical care is understanding the molecular basis for therapeutic resistance as a major cause of long term treatment failures. In cases of melanoma, the main targeted therapeutic strategy is directed against the mitogen-activated protein kinase (MAPK) pathway. Unfortunately, in the vast majority of these patients, resistance to MAPK inhibitor therapies develops within one year of treatment.
In a new study from Boston University Chobanian & Avedisian School of Medicine, ...
Pandemic lockdowns and water quality: a revealing study on building usage
2024-02-01
During the COVID-19 pandemic, lower occupancy in buildings led to reduced water use, raising concerns about water quality due to stagnation. Government warnings highlighted increased risks of chemical and microbiological contamination in water systems. Studies showed that reduced usage and stagnation could elevate heavy metal levels and decrease disinfectant effectiveness, affecting microbial growth. To address this, regular fixture flushing was recommended, which temporarily improved water quality but also revealed the complexities of managing building water systems effectively.
In a recent study (https://doi.org/10.1016/j.ese.2023.100314) ...

As cancer therapies improve, more patients with rectal cancer forego surgery
2024-02-01
While surgery to remove rectal cancer can be necessary and lifesaving, it can sometimes come with significant drawbacks, like loss of bowel control. According to a study led by Wilmot Cancer Institute researchers, patients with rectal cancer who respond well to radiation and chemotherapy are increasingly foregoing surgery and opting for a watch-and-wait approach.
The study, published in JAMA Oncology, shows that the number of patients opting out of surgery rose nearly 10 percent between 2006 and 2020. These data reflect a shift toward what ...
Stanford Medicine-led study shows why women are at greater risk of autoimmune disease
2024-02-01
Somewhere between 24 and 50 million Americans have an autoimmune disease, a condition in which the immune system attacks our own tissues. As many as 4 out of 5 of those people are women.
Rheumatoid arthritis, multiple sclerosis and scleroderma are examples of autoimmune disorders marked by lopsided female-to-male ratios. The ratio for lupus is 9 to 1; for Sjogren’s syndrome, it’s 19 to 1.
Stanford Medicine scientists and their colleagues have traced this disparity to the most fundamental feature differentiating ...

Jealousy – we understand our own sex best
2024-02-01
We may not always fully understand why our partners get jealous, and women and men often get jealous for completely different reasons.
Two researchers from the Norwegian University of Science and Technology (NTNU) decided to investigate whether people also know about these distinct differences between the sexes.
“What do people think triggers women’s and men’s jealousy? How well do women understand men’s jealousy, and men women’s jealousy? We wanted to find out,” says Professor Mons Bendixen at the Department of Psychology.
Men are more jealous ...
Hiring the most qualified candidate might be unfair
2024-02-01
WASHINGTON — Both liberals and conservatives are more likely to believe that merit-based hiring is unfair after learning about the impacts of socioeconomic disparities, according to a study published by the American Psychological Association.
People from across the political spectrum also are more likely to support programs that encourage socioeconomic diversity after learning about the effects of social class and low income, according to the research, published online in the Journal of Experimental Psychology: General.
